摘　　要：采用4种不同粒级的改性高岭土填充丁苯橡胶,制备高岭土/丁苯橡胶复合材料,通过FT-IR对改性高岭土进行表征,采用SEM分析了高岭石颗粒的形态和细度对橡胶复合材料力学性能的影响。结果表明,高岭石颗粒细、片薄的A-1和A-2样,改性后制备的复合材料,其力学性能明显优于粒度相对较粗、片厚的A-3,A-4样;剥片不仅使高岭土中高岭石颗粒粒度变小,且填充橡胶后高岭石颗粒分散均匀,片状取向定向排列,高岭石和橡胶基体结合紧密,发挥了片状晶形的补强作用。Styrene-butadiene rubber was filled with four different size fractions of modified kaolinite particles. Combining the mechanical properties of composite materials, the effect of microstructure of modified kaolinite particles on the mechanical properties of rubber composites were investigated. The results of FT-IR and SEM show that the mechanical performance of the composite material loaded with A-1 and A-2 samples are better than loaded by A-3 and A-4. While A-1 and A-2 are fine particles, thin slices, A-3 and A-4 are relatively coarse grain size, slice thickness. The stripping kaolinite particles are uniformly dispersed and directional arrangement in the rubber matrix. Kaolinite were linked tightly with rubber matrix, and the lamellar crystal playing a role of the reinforcement.
